Modern Clickteam games are harder to decompile due to several engine updates: 2.5+ Changes:
Understanding the logic of a game enables better modding, allowing the community to enhance or extend the functionality of beloved games. What Defines a "Better" Decompiler?

It depends on jurisdiction and intent:
Developers often need to recover specific assets—sounds, images, or graphics—from their own older projects.
However, the CTFAK organization has officially ceased the development of new and existing projects , marking CTFAK 2.0 as “End of Life”. While the source code remains available for archival and reference, users should not expect active support or new features. The CTFAK-UnEx (Unfinished Experiment) branch further highlights this status, with its developer noting it “works far better for some games” but was never stable enough for a full release.
A superior tool preserves object properties, alterable values, qualifier assignments, and global variables. Knowing an object was a "Active Object" is good; knowing it was part of a specific qualifier group and had 50 alterable values assigned is better [2]. 3.

Because Clickteam wrote the runtime, their internal tools can reconstruct the .mfa file with the highest possible accuracy.
No discussion of decompilation would be complete without a frank acknowledgment of its ethical and legal landscape. It is absolutely critical to understand that decompiling software or games is a legal gray area at best and, in many cases, a direct violation of the software's End User License Agreement (EULA).
The release of FusionDecompiler had a significant impact on the game development community. Developers could now decompile and analyze games, gaining a deeper understanding of how they worked. This led to a surge in modding and game modification, as developers could now build upon existing games and create new content. The decompiler also helped identify and fix security vulnerabilities, making the community a safer and more secure place.

While many tools claim to be the "best," the landscape of Clickteam Fusion decompilers is a mix of community-driven projects, technical hurdles, and legal controversy. The Evolution of Clickteam Fusion Decompilers
For years, developers who lost their original project files (MFA files) were often stuck with uneditable executables. Early tools were rudimentary, often extracting only raw assets like images and sounds while leaving the logic—the "events" that make a game work—unreachable. The demand for a "better" decompiler grew not just from a desire to mod popular games like Five Nights at Freddy's , but from a practical need to recover years of lost work. The Evolution of Tools
The following table compares the two primary modern decompilers, highlighting what makes a tool "better" for different user needs.
Before diving into the tools, it’s essential to understand what a decompiler needs to handle. Clickteam Fusion 2.5 projects are typically saved as .mfa (Multimedia Fusion Application) files, which store all frame data, events, images, sounds, and object properties. When distributed as a game, these projects are compiled into a standalone .exe (Windows), .apk (Android), or other platform-specific formats, which are usually compressed and encrypted. A decompiler must reverse this process, parsing through the proprietary compression and encryption algorithms to reconstruct the original assets and, ideally, a functional .mfa project file.
